[Rational range and optimum proportion of energy input in farmland]

Area of Science:

• Agricultural Science
• Agronomy
• Soil Science

Context:

• Optimizing artificial supplemental energy inputs is crucial for enhancing agricultural productivity.
• Understanding the rational ranges for energy, water, and fertilizer is key to maximizing crop yields and resource use efficiency.

Purpose:

• To determine the rational range of artificial supplemental energy inputs for improving crop yield and output/input ratio.
• To identify optimal strategies for water and fertilizer application to maximize efficiency and economic returns in agriculture.

Summary:

• A rational range of artificial supplemental energy inputs improves crop yield and the output/input ratio, with greater benefits observed in lower-yielding fields.
• Within this rational range, high-efficiency lines for water and fertilizer inputs exist, achieving maximum efficiency when inputs align with these lines.
• Optimum proportions for energy and economic inputs in water and fertilizer application were identified, maximizing output/input ratios.

Impact:

• Provides insights into maximizing agricultural production through efficient resource management.
• Offers guidance for farmers on optimizing energy, water, and fertilizer use for increased profitability.
• Contributes to sustainable agricultural practices by highlighting efficient input strategies.
